In response to the continuous improvement of requirements for distribution network management,accurate calculation of line loss is becoming increasingly important.Therefore,this article introduces three calculation methods:equivalent resistance method,split phase equivalent resistance method,and voltage loss rate method.An actual three-phase unbalanced low-voltage distribution network is selected as a case study.Through analysis,it is found that when calculating the load of three-phase unbalanced low-voltage distribution network,the calculation results using the sub item equivalent resistance method are the most accurate,which can improve the economic benefits of power supply companies and has certain application value.
